Abstract

FaceTime and other encrypted network calling tools pose new fraud risks, and the traditional SIM card monitoring system lacks adaptability. Based on the "Five-in-One" anti-fraud practical experience of Guangdong Mobile, this study constructs a fraud monitoring and disposal technical framework for encrypted communication scenarios, analyzes core technical application logic such as DPI deep parsing, multi-source data fusion, and AI-assisted judgment, and verifies its effectiveness in reducing fraud-related numbers and intercepting fraud losses. Research shows that the system integrating multi-source network data and AI decision-making can achieve accurate identification and efficient disposal of fraudulent behaviors in encrypted communication scenarios, providing practical support for the improvement of network anti-fraud theory.
